      drm: move pci bus master enable into driver. · 466e69b8
      Dave Airlie authored
      
      
      The current enabling of bus mastering in the drm midlayer allows a large
      race condition under kexec. When a kexec'ed kernel re-enables bus mastering
      for the GPU, previously setup dma blocks may cause writes to random pieces
      of memory. On radeon the writeback mechanism can cause these sorts of issues.
      
      This patch doesn't fix the problem, but it moves the bus master enable under
      the individual drivers control so they can move enabling it until later in
      their load cycle and close the race.
      
      Fix for radeon kms driver will be in a follow-up patch.
